These instructions are to completely delete everything Sims related from your Mac – CC/Mods/Saves/Downloads, everything (to manually uninstall a single EP/SP please read this guide). If you’re having problems with your game this is a last resort but it will only work if you really get rid of everything. Even then it’s not 100% guaranteed that your game will work again after reinstalling but it should give it the best chance possible. A lot of Preference files are left behind when you uninstall The Sims 3 using the Uninstaller in the Applications folder. In order to make sure you have a completely clean uninstall of the game, follow the steps below.
Please note that the Preferences folder has really important files in it so make sure you don’t delete ANYTHING apart from the files mentioned below. You can render Applications useless and potentially screw up the OS by deleting the wrong things. This is why Apple have hidden it from Lion onwards.
– If your Uninstaller isn’t working or has mysteriously disappeared you can still follow these steps but you must firstly trash your TS3 Applications and user data. To do this go to Finder > Applications and drag The Sims 3 folder to the trash. Remember to trash any shortcuts you have in your Dock and/or on your Desktop too. Next, go to Finder > Documents and trash the Electronic Arts folder. If you have other EA games in there DON’T trash this folder, instead open it and just trash The Sims 3 folder.
– If you have the Uninstaller use it to uninstall all your EPs, SPs and the Base Game. When you have deleted all of these you need to do the following:
For Leopard/Snow Leopard users:
– Open a Finder window, click on your Home/User folder (the one with the picture of the house next to it), open the Library folder in the right-hand pane then open the Preferences folder.
For Lion/Mountain Lion/Mavericks/Yosemite/El Capitan/Sierra users:
– Make sure you are in Finder by clicking anywhere on the Desktop, it will say Finder in the menu bar, next to the Apple logo.
– Click on Go. When the dropdown box appears press the Option key (alt) on your keyboard. The Library folder will now appear. Click on Library then open the Preference folder.
In the Preferences folder delete a folder called Cider Preferences, if it is still there, and The Sims 3 Preferences folder, if it is also still there. Now you need to delete any files that have Transgaming and Sims in the name. They will start with com.transgaming…… in the file name and look something like this:
Next, open the Caches folder in the Library folder and delete all folders that start with com.transgaming. In the Cookies folder (same Library folder) look for a file beginning with com.transgaming… and delete it (thanks to CPUGenuis at AHQ for finding that one!).
Note for Lion, Mountain Lion, Mavericks, Yosemite, El Capitan & Sierra users – In the main Library folder there is a folder titled Saved Application State. In there you may also see a whole load of folders that look like this:
As you can see they have transgaming in the title. You need to delete these too. Thank you to kaosgirl and Snapdragon over on the official forums for bringing this to my attention. Now you should empty your Trash. Restarting your Mac wouldn’t hurt either.
Once you’ve done all that you can start reinstalling the game again, patching after the Base game and each subsequent EP and SP if prompted. It is always advisable to patch using the super patch. Just to be on the safe side I always reinstall in the order the EPs and SPs were released:
- The Sims 3
- World Adventures (EP01)
- High End Loft (SP01)
- Ambitions (EP02)
- Fast Lane (SP02)
- Late Night (EP03)
- Outdoor Living (SP03)
- Generations (EP04)
- Town Life (SP04)
- Pets (EP05)
- Master Suite (SP05)
- Showtime (EP06)
- Sweet Treats (SP06)
- Diesel (SP07)
- Supernatural (EP07)
- Seasons (EP08)
- 70’s, 80’s & 90’s (SP08)
- University Life (EP09)
- Island Paradise (EP10)
- Movie Stuff (SP09)
- Into the Future (EP11)
